Cool, Spranger and Sindri got the two approaches I was thinking about on the table. I bet 2/3 pot on the flop - later it occured to me that maybe I should've checked behind.
I'd thought from the pf action that AK and JJ+ (maybe even TT) were all in his range - I guess he either had TT or AK, since he snap folded, I don't see him folding AA or KK that quickly.
I was also a little worried about the wet flop, and didn't want to give a fd or AK a free turn card - as Spranger says, I wonder if I shouldn't have let him have that card... But, as Sindri says, I'm not crazy about the turn action if a T or a club shows up...
If you don't mind one more question here, could you compare this to the logic of calling in position in this post from Bob_Tiger? http://www.cardschat.com/f50/100nl-flopped-set-position-dry-board-143270/ Obviously the situation Bob describes is different since Villain leads out and the board is dry, but if calling behind in Bob's scenario is a good approach to that situation, is checking behind in this scenario a good approach to this situation?
